Hey guys,
Now that I've fixed the fuel leak and petcock on my little 50cc 1963 BS-7, I'd like to try to get it running a bit better. It tops out at about 29mph, and that's downhill.
So far I've tried: 1) Using better fuel and additive, 2) cleaning the tank and the carb, 3) raising the idle (it's so erratic though, I'm not sure i actually raised it. Clockwise on the screw raises it I think?)
Anyway, so far no dice, stays about the same. I'm thinking it may be a compression problem. But before I mess with remachining the cylinder, I thought I'd ask you guys. Could it be something simple like the throttle cable needing to tighten? Or is it maybe that a 180 lb man on a 50cc machine from 5 decades ago just isn't gonna go more than 30?
Thanks,
Matt
